Me and rogro82 started to port Android 4.2 to the HTC One X

  • Wireless
  • Phone calls
  • GSM Data
  • Audio
  • Video Playback (including HD)
  • Camera (no photosphere - blame google)
  • GPS
  • NFC
  • Bluetooth
  • BT and Wireless tethering

Not Working
  • USB tethering (?)

Installation instructions
  • Verify that your backup is complete - a backup of your sdcard may also be a good idea (see below)
  • Verify that you are running hboot 1.26 or newer (hboot 1.39 is recommended)
  • Download the ZIP and the boot.img (see Downloads)
  • Copy the .zip to your sdcard and reboot into fastboot
  • fastboot flash boot boot.img, then boot into recovery
  • WIPE your phone (this is not optional)
  • Install the .zip and reboot

You can always upgrade to a newer version without wiping any data, formatting system or wiping the cache.
But keep in mind that you must always flash boot.img + re-flash gapps after upgrading


RC20 (20130825)
  • Fixed the two Android 'master key' bugs
  • Kernel patch for CVE-2013-2094
RC19 (20130317)RC18 (20130311)
  • Option to control button backlight depending on the screen brightness (Settings -> Display)
  • Software fix for pabx's broken headphone jack detecion: Added an option to forcefully route mediaplayer-output to the headphone jack. (Settings -> Audio)
RC17 (20130301)
  • Use latest WIFI Firmware (improves reception)
RC16 (20130216)
  • Added to build.props. The phone will now only accept ADB connections from authenticated hosts. Note that you must upgrade your local ADB installation to the version included in the 4.2.2 SDK. Connecting with an pre-4.2.2 adb will not work
  • Fixed quicksettings: longpress = toggle, press = settings
  • Internal: Use CMs nicer audio-recording patch
RC15 (20130213) Android 4.2.2
  • Upgraded to Android 4.2.2_r1
  • Silenced vibrate kernel driver + removed unneeded pm_qos request
RC14 (20130208) Kernel 3.1.10
  • First release with Linux 3.1.10. Note that you MUST upgrade your hboot to 1.3x (1.2 versions may work - any feedback is appreciated, but any version < 1.2 will NOT work - your phone will freeze during deepsleep!)
  • Mounting USB-OTG devices on 4.2 is somewhat tricky as filesystems are not shared with 'parent' processes - using some userspace app like 'Nexus Photo Importer' is recommended
  • Switched to ondemand govenor as the old 'interactive' is broken in HTCs Linux 3.1.10 source drop (doesn't make a big difference)
RC13 (20130202)
  • Merged missing cam pull request
  • Option to change the max frequency in settings (Developer Options -> CPU Frequency)
  • Improved frequency management - say goodbye audio dropouts!
RC12 (20130122)
  • More camera options (jpeg quality, burst mode, scenes) - thanks to seadersn
  • Option to enable the overflow button

RC11 (20130114)
  • Support for encrypted /data partition. (see this post)
  • Ability to limit the max CPU frequency (see this post)

RC9 (20121229)

  • Bluetooth Audio (A2DP) is now working
  • Stubborn BT devices should now be able to pair
RC8 (20121225)
  • Fixed WIFI Tethering
  • Changed halo background
RC7 (20121220) Doomsday edition
  • Bluetooth Tethering support (still a little bit flaky, try to re-enable bluetooth + tethering if the connection drops)
  • Changed quicksettings behaviour: Short press = toggle / Long press = open settings
  • Reboot + Screenshot options in Power-Off menu (thanks to lownoise2)
RC6 (20121219)
  • Support for Bluetooth file transfer and HID (Again: thanks to rogro82)
RC5 (20121215)

Gapps download

I can not upgrade my hboot to 1.3x, help!

You can still run RC13:
This was the last release using Linux 2.6 and will therefore work on older hboot versions. RC13 is stable enough for everyday-use.

What kernel should i use?

Use the stock kernel from boot.img - there is nothing wrong with it. Using a different boot.img or/and kernel will just break stuff.

Even more links!

For people wondering:

Although its an AOSP build it does have multi-user support which originally is only available on tablets in AOSP ( users can be added in settings )

Will have to give this one a shot. Looks very interesting, even though there's some major flaws. Official CM10 has never been stable on the HOX, so looking for alternatives. AOSP might be the solution, in the long run (not currently in that state ).

Good luck with the upcoming work, attempts, hacks, tweaks etc.!

1. You can add NFC to the list of working things. Just tested it with a tag.
2. The performance of the ROM seems very snappy and nice. Just because of it I had to take a few benchmark tests, and yeah, the ROM performs! (oops, wasn't made public at first)

Generally about Android 4.2 and its new quick settings (QS):
I wonder why Google doesn't allow us to reorder the grid (by long pressing on the items, much like on their launcher; folders). Would be great if one could add or remove buttons too. Personally I'd like to add GPS + NFC and remove 'Airplane mode'. When tapping on the items their respective activities is started. Convenient sometimes, but it makes QS pretty much useless... On/Off toggling would've been the preferred way I think. Much like how the Airplane mode button works... it doesn't even ask the user if the device should be put in airplane mode (which I think is pretty vital).

Definitely wanna try, but will probably wait until it's a little more stable.

Needed to rename rc0.boot_img to rc0boot.img (really any .img name would work) but otherwise booting fine straight over the top of latest CM10 nightlies. I'm no dev, but love being on the bleeding edge

Yes this is hboot related ( i will notify pabx to put this in the first post )

To everyone:
Please feel free to post bug reports ( if not already mentioned in the first post by pabx ) and in case of a crash a logcat would be great
